What happened: 49ers fullback Kyle Juszczyk has been fined for his signature chugging celebration. The NFL deemed the gesture an offensive demonstration following Sunday's game against Miami.

Why it matters: Juszczyk noted that the celebration is an ode to his nickname "Juice" and that he has done it his entire career without penalty. He texted that he does not even drink beer.

What to watch: It remains to be seen if Juszczyk will modify his signature celebration going forward.
